TICKLIN G MACHINE.

Application filed September 9, 1924. ,Serial No. 736,717.

To all whom it may concern."

Be it .known that I, LEIF LEE, a citizen of the United States, and a resident of You'ngs 'town, in the county of Mahoning and the State of Ohio, havemade a new and useful Invention in Pickling Machines, of which the following is a specification.

This invention relates to pickling machines and more particularly to an improved form of mechanism for-supporting and agi'- tating articles in a pickling bath.

Pickling machines, as heretofore constructcd, generally consist of a vertically cated in structure, due to the necessity for such devices as fluid pressure pumps, vaives and the like, and, consequently, is expensiveboth to construct and operate.

An object of this invention is to provide a simplified and improved form of mechanism for supporting and agitating articles in a pickling bath, which is rugged but at the same time an improvement both from the standpoint of structure and operation.

A further object is to provide a mechanism for the purpose set forth-which can be p directly operated from any convenient power shaft and in which such operating devices as air pumps, valves, storage reservoirs and the like are entirely eliminated. j I

These and other objects which will be apparent to those skilled in this particular art are attained by means of apparatus embodying this invention, one form of which is shown, in the accompanying drawings, in

Figure 1 is a plan view and Fig. 2 is a side elevation ofthe illustrated embodiment.

The particular embodiment of this inven cate supports on which trays are so supported that they are submerged in' the pick- -ling or washing solution. The supports are so constructed and arranged that the trays may be readily and easily suspended from' them, and they are also of such character that the oscillatory movement of the walking beams is imparted to the trays as a vertical reciprocatory movement.

The drawings show two pickling baths 5 and 6 which are supported in any desired manner upon a suitable base 7. Bearings 8 and 9 are mounted in spaced relation between the pickling baths on a suitable standard 10, which is mounted on'the base 7 between the baths 5 and 6, and extends above the surfaces of the baths. A shaft 11 is journaled for oscillatory movement in the bearings and the shaft is provided, at its outer ends, with parallel arms or walking beams 12 and 13.

Each end of each Walking beam is con- I nected by means of a link 14, to a slide block 15 mounted in vertical guideways 16. Each slide block has an inwardly facing pocket 17 formed in the top thereof for receiving one end of a rod 18 which supports a tray 19 in such a position that it is submerged by the liquid or ntained in the bath. As illustrated, each set of guideways 16 is mounted on one end of one of the baths, although it willbe apparent that the guideways may be p independently supported adjacent the ends of the baths.

Each rod 18 has a collar 20 adjacent each end thereof on which are formed lugs 21 and 22. Springs 23 and 24 are secured to the lugs, and cables 25 and 26 which support the trays are secured to the lower ends of the springs 23 and 24, respectively.

Agitation. of the articles in the pickling solutions is obtained by oscillating the shaft 11. through the medium of a crank arm 27 w ich is shown in Fig. 2 as'forming a part of the walking beam 12 but which may obviously be separately formed and connected -to the shaft 11 in any desired manner. A

connecting rod 28 connects the outer end of the crank arm with a crank 29 formed on any desired power shaft" 30. The shaft 30 may be driven from any convenient source of power such, for exam is, as an electric motor 31, the shaft 32 0 which drives the shaft'l30 through. the medium ofwormwheel 33. The power shaft 30 may be provided with a clutch 34 for disconnecting it from the motor at any time.

In operation, the tray 19 is positioned in a pickling bath by lowering the supporting rod '18 into the pockets 1? formed in the tops of the slide blocks. Any suitable form of overhead crane may be used for this purpose. Rotation of the shaft 30 oscillates the shaft 11.so as to agitate the articles in the bath and at the end of the operation the rod 18 and container 19 may be lifted out of the bath and transferred where desired. The springs 23 and 24 prevent undue jarring of the articles in the container andaccentuate the motion transmitted to the container by the oscillating shaft. It is obvious that the trays on opposite ends of the walking beams counterbalance each other and that a minimum amount of power is expended in operating the apparatus. In addition, the trays are reciprocated vertically while in the bath solution and this eliminates splashing and slopping of the solution. The apparatus may also be applied to many standard forms of pickling and washing baths, thus eliminating the necessity for speciallyconstructed baths.

Although I have described in detail but one embodiment of my invention, I do 'not wish to be limited to the specific structure shown but what I claim as new and desire to secure by Letters Patent is:

1. The combination with a pickling bath,

of an oscillatory shaft, parallel arms secured to said shaft, a reciprocating member secured to one of said arms at each side of said bath and means for detachably supporting a container on said member for immersion in said bath. Y

2. The combination with a pickling bath, of a. vertically reciprocating slide-head above each end of said bath, pockets formed in said slide-heads, means for detachably supporting a container from said pockets for immersion in said bath, an oscillatory shaft positioned adjacent said bath, and

means for reciprocating said slide-heads from said shaft.

3. The combination with'a pickling bath,

'of a vertically reciprocating slide-head mounted adjacent each end thereof, ockets formed in said slide-heads, means or de..-,

tachably supporting a; container in said"ber,1924;.

pockets for immersion in said bath, an oscilsaid bath, slide-heads adapted to reciprocate above said member, and means for yieldingly supporting a container from said slide-heads for immersion in said bath.

5. The combination with a pickling bath, of an oscillatory member mounted above said bath, a slide-head at each end of said bath adapted to be reciprocated by said member, a pocket formed in each slide-head, a rod adapted to be removably seated in said pockets and yielding means for supporting a container from said rod for immersion in said bath.

A 6. The combination with two pickling byaths, of an oscillatory shaft positioned between said baths, a slide-head at each end of each bath, parallel 'walkin beams secured one at each end of said sha t for reciprocating said slide-heads, a pocket formed in the top of each slide-head, andmeans for supporting a container in each bath from the pockets of the associated slide-heads.

a pocket formed in the top of eachslidehead and means for resiliently supporting a container from the pockets of adjacent slideheads at each end of said beam for immersion in said baths.

8. The combination with two pickling baths of an oscillatory shaft positioned between said baths, a slide-head positioned abO"6 the end of each of said baths, parallel walking beams secured one at each end of said shaft for reciprocating said slide-heads, a pocket formed in the top of each slide head, a rod adapted to extend longitudinally above each bath and to rest in the pockets of the associated slide-heads and means for resiliently supporting a container from each of saidrods for immersion in the associated bath. l I

In testimony whereof, I have hereunto subscribed my name this 4th day of Septem- LEIF LEE.
